- UNITED, STATES PATENT OFFICE,

ojA'RL LORENTZ NILsoN, OF MONTREAL, QUEBEC, CANADA.

LoooMo'rIvn.

To all whom 05mm Be it known that I, CARI LORENTZ NILSON, a subject of the King of Sweden, residing atMontreal, in the Province of Quebec, Dominion of Canada, have invented certain new and useful Improvements in Locomotives, of which the following is a full, clear, and exactv specification, reference being had to the accompanying drawings, and, to the reference characters markedtives whiclrare employed on rails or tracks and for moving cars or trains thereon for the ordinary purposes of transportation of passengers and freight. This class of devices. issometimes designated railway locomotives.

The object ofmy' invention is principally to make a very long and very heavy locomotive calculated to be operated at a high speed and to have great power of .traction under an economical consumption of steam and at the same time be capable of operation upon railways having the usual curves and without danger of derailment or inconvenience of movement by reason To accomplish the foregoing object and to secure other and further advantages inthe matters of construction and operation, nay-improvements involve certain.

newand useful arrangements as will be herein first fully described and then pointed out in the claims.

In the accompanying drawings forming part of this specification, Figure l is a view in side elevation of my improved-form of locomotive, and Fig. 2 is a corresponding front end elevation. i

In both figures like letters of reference, whereverthey occur, indicate corresponding parts.

As indicated, the locomotive structure is un ually long; and that it maybe correspondingly heat; and powerful I surround a portion of the boiler" ith a jacket,

represented at A within which asupply of water is carried, and outside the fire bori and combustion chamber proper is another jacket, represented at B, within which to carry a supply of fuel. This latter jacket will I preferably be somewhat angular in construction while the former may most conveniently be made cylindrical.

- The weight of the water and the fuel are added to the weight upon the driving wheels and thus increase the traction of the locomotive. A cab, C, for the engineer and firemanis embodied in the structure,'as usual.-

I sustainfthe weight of the boiler and its immediate appendages upon two independent trucks, called the forward truck andthe rear truck, and these trucks are movable beneath the body of the structure after the manner of ordinary railway car trucks so as to conform to the variations ,in the curvatures of the railway and thus enable the long body to be turned about or moved along or; over a curve of comparatively short radius,

- I which would otherwise be impossible or dangerous. 1

. Specification of Letters Patent. Application filed August 25,1906. Serial 110,332,027.

Patented July 16, 1907.

The king bolt or pintle of the forward truck is represented at ii, the rear truck having a similar king bolt or pintle, not shown.

D, D, D and D are the wheels of the forward truck which are utilized as driving wheels. They are connected by a connecting bar or drivingbar E; and this baris actuated by a connecting rod F journaled as at b on the bar E and suitably jointed with a cross-head, H,

movable in or on a slide,I, at the rear portion ofthe truck by yokes, as M, which may be formed in substantially the same way as are the yokes L. i The crosshead' H is driven by a connecting rod, N, coupled with said cross-head and with a cross-head O which in turn is connected with the piston rod, P, and moves upon a suitable slide represented, at Q. Inasmuch as the cyl-' inders K, K, are movable with respect to the locomotive boiler, a peculiar means of delivering steam from v the boiler to these cylinders are necessary.

R, R, are steam delivering pipes leading from any convenient steam spacet within the boiler as may be preferred. For the front cylinders these pipes are carried down to a suitable union joint, represented at c,

.and from this union or coupling which permits the desired movements of the branches, branches as R, R

lead to the steam chests of the cylinders.

The pipe coupling '0 is located over the pintle or, king bolt a so that the axis of the pipe coupling andthat of the king bolt are co incident. This arrangement providesf orthe movements of the'branches R R ,simultaneously with those of'the truck and therefore with thoseof the two cylinders, whereby any'cramping and consequent damage is obviated and steam is supplied to the cylinders in the same manner asif they were rigid in" respect to the boiler.

- The wheels of the rear truck are represented at D D D and D and these wheels like those of the forward truck are also utilized as driving wheels. They are connected on ea h side of the truck by a similar driving bar E} operated by a coupling rod F united with a cross-head H movable upon a slide I.

K represents one of the cylinders connected with the 7 rear truck and this is secured and sustained upon the rear truck upon the same general principles as the forward cylinders are secured and sustained. The slides I (on each side) are rigidly secured upon orin connection with the-rear truck by suitable yokes, as M res.-

which may be formed same as the yokes L or. M. The

cross-head H is driven by a connecting rod N- which joins said cross-head and a cross-head 0 made movable by the piston rod P; Steam pipe branches as R lead to a pipe coupling, as 0 which should be located over the vertical axis of the rear truck; and from this coupling branches, as R conveysteam to the steam chests of the cylinders K The cylinders on either truck may be utilized independently of-those on the other, or both sets niay be simultaneously employed, as will be apparent. The cylinders on the iorward truck are preferably located in front and those in the rear truck atthe rear; but this arrangement is-not essential and may be varied at will. The forward cylinders are preferably larger than the rear cylinders, and this affords the advantage oi using only the small cylinders when but little power is required to be exerted, thereby effecting a saving in the consumption of steam and fuel. The engine cylinders 20."

are located.abo've theilevel of the axles of the truck I wheels and iorthe most part higher than the wheels;

and the arrangement of connecting rods enables me to I employ wheels of anydesired diameter without impairing the strength of the structure or the driving The parts being constructed and assembled as herein indicated, the improved locomotive will be found to answer all the purposes or objects of the invention herein alluded to.

' Having now. fully described my invention, What I claim as new herein and-desire to secure by Letters Patent, is: I

'1. In a locomotive, the combination with the boiler and fire box, of a jacket around the boiler forming a compartment for'water and a jacket surrounding the fire box torining'a. compartment for fuel, the independent trucks. and :1 steam conduit having connected branches and joints, one joint being located over the center of the forward truck and one over the center of the rear truck, substantially as and for the purposes set forth.

2. In in locomotive, the combination of a truck, an engine cylinder secured thereon outside the wheel line and extending above the wheels at one end of the truck, the piston rod, a coupling rod connected with the piston rod. a crhss head on the end of the truck opposite the cylinder. a yoke for sustaining said cross head, a coupling bar 'extending from the cross head towards the opposite end of the truck, and a driving bar c'onnectingall the wheels. the second coupling rod-being connected with said driving bar and cross head, the parts being mounted and arranged substantially as set rth.

' In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses.
